PowerECal - Power Electronics, Power Supply and Magnetic Engineering Calculator includes the magnetic formulas calculation, units conversion and wires conversion tables. It's a very useful tool for power electronic engineers.
Calculators: Transformer / Inductor / Magnetic flux density Calculator - which can calculate peak flux density(Bp) against peak current Ip or voltage Von and duty cycle Don;
Temperature Rise vs Air flow Calculator - which can calculate Velocity and Volume needed for the air flow through a box. By inputting cross section dimension, power dissipation(Pd)inside the box and temperature rise(dT) of the outlet air flow, result can be shown according to the provided illustration.
